摘要
成矿单元/成矿区(带)是指导矿产勘查的资料和理论依据,其重要性及实用价值早有共识。国外自20世纪初开始探索研究,至今已有100多年的历史,经历了成矿单元/成矿区(带)概念的形成、发展成熟和多元信息应用3个阶段。我国成矿单元/成矿区(带)的探索研究工作与国外同步进行,获得的成果为我国和全球成矿区(带)级别、区带定位、各级区带内涵的标识和矿产勘查结合等方面作出了杰出贡献。国内外资源"瓶颈"新形势的迫逼,推动了我国成矿单元/成矿区(带)的全面研究,获得的成果概括为:"界面成矿"的区域成矿学新理论,多元成矿信息识别和提取的技术方法,细化成矿单元/成矿区(带)级别划分(Ⅰ—Ⅸ级)并赋予各级成矿单元/成矿区(带)地质理论解释内涵等。经多年勘查实践,又提出了细化Ⅰ、Ⅱ、Ⅲ级成矿区(带)内区域成矿规律的研究(平面和立体);对Ⅴ、Ⅵ、Ⅶ级成矿区(带)(有些地区包括Ⅵ级)的边界要准确划定,实施四维空间成矿信息的搜索、识别和提取,为整装勘探和深部勘探提供资料和科学依据;Ⅷ、Ⅸ级成矿单元作精细评价,必须为矿床的工业评价和采、选、冶提供有价值的科学依据,达到经济、综合开发和利用矿产资源的目的。
It had reached an agreement that as an important and valuable scientific basis, the concepts of metallogenic unit and metal- logenic belt could be used to instruct mineral exploration in the geological field worldwide. Since the beginning of the 20th century, there existed three stages such as formation, developed mature and multi-mineralization information application of metallogenic unit/ metallogenic belt during a long seeking course, China kept its pace with the world in the study of metallogenic unit/metallogenic belt, obtaining outstanding contributions in classification, location of metallogenic belt, meaning signs combined with mineral exploration in the belts at all levels in the world. The comprehensive study of national metallogenic unit/metallogenic belt was forced by severe situa- tion of resources both at home and abroad. It could be summarized as a new regional metallogenic theory, i.e. interfacial mineraliza- tion; technical methods of identification and extraction of muhi-metallogenic information; classification （grade I -IX ） and interpretation of geological theory of metallogenie unit/metallogenic belt at all levels. It was effective for those theories and methods according to field exploration of many years. At present, the authors put forward three new missions ： （ 1 ） deepening the study of regional metallogenie regularity（planar and three-dimensional） in the metallogenic belts with grades I, II and III ; （2） accurate classification of boundary of grades V, VI and VII metallogenic belts and seeking, identification and extraction of metallogenic information of four-dimensional space ; （3） careful evaluation of grades VIII and IX metallogenic units, then, reliable and valuable data on development and utilization of min- eral resources scientifically could be provided on the basis of the above study results.
